CLOTH-BOARD WIN'DERI.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed November 17, 1915. SeriaINo. 61,932.

To all whom it may concern J Beit known that I, Gnonon W. DINSMOOR, acitizen of the United States, residing at Lawrence, in the county ofEssex and State of Massachusetts, have invented new and usefulImprovements in Cloth-Board Winders, of which the following is aspecification.

This invention relates to cloth-board winders and its object is toprovide improved means for holding, rotating, 'andreinforcing acloth-board.

Cloth-boards areused by weaving mills to Wind the cloth into bolts forstorage and shipment. Such boards have been made of Wood, hitherto, andalthough the latter is satisfactory material it involves considerableexpense. Still a less stable material would not have been usable in thewinding machines now in use, because of the stresses which theboardshave to sustain while in such machines.

My present invention provides a winding machine which braces the clothboard in such manner and to such degree that aboard made of materialmuch Weaker than wood will amply fulfil requirements. Clothboards madeof wood pulp are cheaper than those made of wood in itsnaturalcondition, but are not strong enough to sustain the stresses in thewinding machines hitherto used. A winding machine made according to mypresent invention will brace the clothboard so that even if the latteris made of wood pulp it will be satisfactory.

Of the accompanying drawings which illustrate one form in which theinvention may be embodied: Figure 1 represents a sectionalview in avertical plane through the winding mechanism, a portion of thecloth-board and its holding elements being broken out. Fig. 2 representsan elevation of the complete cloth-board and its holding elements. Fig.3 represents a section through the structure intersected by line 33 ofFig. 2. Fig. 4.- represents a section through the structure intersected,by line 44 of Fig. 2. Fig. 5 represents a view indicated by line 5-5 ofFig. 2. Fig. 6

represents a section indicated by line 66' of Fig.2. Fig. 7 represents asection indicated by line 7-7 of Fig.2. Fig. 8 represents a sectionindicated by line 88 of Fig. 3.

The same reference I characters indicate the same parts Wherever'theyoccur,

The cloth-board is indicated at 10. The Winding mechanism includes apair of rotary headsindicated respectively at 11 and 12, shafts 13 and14 carrying said heads re spectlvely, and a pair of bars 15, 15 from oneof said heads to the other, and other elements hereinafter specified. I

The two heads are driven in unison, and the bars 15, 15 travel aroundthe axis of the shafts 13 and 14 and thus rotate the clothboard asindicated by arrows in Fig. 4. The shafts. 13 and 14 are'journaled inbearings 16 in the frame of the machine. A gear 17 is mounted upon shaft13 and connected to the latter by a key 18. This shaft is held againstendwise movement by collars 19, 19. A gear 20 is mounted upon shaft 1 1and is connected to the latter by a key 21. This shaft is movableendwise in its bearings, for a purpose hereinafter explained, and isprovided with an elongated keyway 22 in which the key 21 may slide.

The heads 11 and 12 are formed respectively with slots'23 and 24 toreceive the bars 15. These bars are connected to the head 12 by bolts25, each bar having in the present instance two bolt-receiving holes 26(Fig. 2) at one end. The head 12 is provided with two series ofbolt-receiving holes 27 arranged at various distances from the axis ofrotation to enable the bars 15 to be set toward or from such axisaccording to the width of thecloth-board It is desirable to set the bars15 so that their outer edgeswill be suhiciently near the winding edges10 of the cloth-board to brace the latter against the winding stress.The outer edges of the bars 15 are preferably beveled as indicated at15', to facilitate their Withdrawal from the bolt of cloth as the latteris removed from the bars.

Referring to Fig. 2, it will be observed that the distance between thetwo bolt-receiving holes 26is greater than the space between adjacentbolt-receiving holes 27 in the head, the difference of spacing affordingtwice as many positions of adjustment as there are holes 27 in eachseries.

The left-hand ends of the bars 15 are movable into and outof the slots23 in the head 11, and in order to facilitate the insertionof the barsinto said slots the surfaces 28 of the head are beveled as shown best byFig. 8. The left-hand ends'of the bars 15 are held at the desireddistance from the axis of rotation by adjustable blocks 30 carried bythe head 11. These blocks are formed with beveled surfaces 31 which bearupon the surfaces 28 of the head. Each block 30 is clamped by means of aclamping bolt 32 and washer 33. Each block is formed with a beveledsurface 34, and these surfaces of each pair of blocks are arrangedtoward each other, as shown by Fig. 1,.to facilitate the insertion ofthe bars 15 into the head 11.

Each bar 15 carries an adjustable clamping member 35 for engaging oneend of the cloth-board. The members 35 have undercut lips 36 (see Fig.6) arranged to overlap the end of the board. The members 35 are boredand tapped for the reception of setscrews 37, said screws being arrangedto bear against the bars 15. The members 35 are capable of sliding alongthe length of thebars 15 to the desired position according to the lengthof the cloth-board, and may be fastened'at any position lay-tighteningthe setscrews.

The left-hand end of the cloth-board is held by a spring-pressedclamping member 38. This clamping member is formed with a groove 39(Fig. 7 adapted to receive the edge of the cloth-board. The clampingmember is formed with a shank 40, and the latter is arranged to slide ina socket bored in the shaft 13. A helical compression spring 41 arrangedin said socket forces the clampingmember toward the right and thus keepso the clamping member against the board as shown by Fi 7, and also keepsthe right-hand end of the board against the clamping members 35 as shownby Figs. 2 and 6. The shank and shaft 13 have pinand-slot connectionwhich prevents the shank from being forced entirely out of its socketwhen the cloth-board is removed, the pin indicated at 42 being set inthe shaft,

and the slot 43 being formed in the shank, This pin-and-slot connectionserves the additional purpose of keeping the groove 39 in position toregister with the cloth-board. I have not shown any means for drivingthe gears 17.and 20, but it will be understood that these gears are inpractice driven in unison. It will be observed that the bars 15, 15 arearranged to bear on opposite sides of the cloth-board and that each isbehind the cloth-board with reference to the direction of rotation, sothat the marginal portions of the cloth-board will be amply braced bythe bars as the latter sustain the winding stress. The stress of theclamping spring 41 must be considerable in order to prevent the boardfrom slipping, and such stress would bend or buckle a comparatively weakcloth-board, such as one made of wood pulp, if it were not bracedagainst such buckling stress. The structure shown affords the necessarybracing in this respect,

forfthe' lips 36 of the clamping members '35 hold the rightrhand end oftheboard firmly against the bars 15, and the bars brace the marginalportions of the board' throughout the length of suchportions. In-

asmuch as the bars are against opposite ing the shaft inworkingposition. Refer:

ring to Fig. 1, at the outer end of the shaft 14 there is a pair ofcollars 44. These col-- lars are pmned or otherwise-aflixed to the Vshaft. An operating lever 45 carries a pair of studs 46 arranged in linewith each other and diametrically opposite with relation to the axis of,the shaft. 7 These studs project into the space between the collars 44.V The lower end of the lever 45 is mounted upon a fulcrum stud 47, andthe upper end. of

the lever is provided with a handle 48.: 'A

latch 49 is mounted upon the frame of the machine by means of a pivotpin 50. 'The lever 45 is formed with ahole 51 through which the outerend of the latch may pass. V

When the parts are in working position as shown, the latch hooks over ashoulder 52 011 the lever.

Assuming that a cloth-board; is set in the wlnder and that the latter isadjusted for winding, the board will be rotatedas her'ein-- beforestated until the desired quantityof cloth has been wound. In'order toremove the cloth-boardv together fwith the cloth wound thereon theattendant lifts the latch 49 ,to release the lever 45; ThelheadlQ andshaft 14 will then be forced back-by the compressed spring 41, but theattendant may complete the retraction of the head and the shaft byswinging the handle 48'to the right. The left-hand ends of the bars 15will thus be withdrawn from the hea'dll, but an attendant will take holdof the bolt of cloth at such time so that it will not drop .When.the'bars 15 have thus been freed from the head 11 they may swing aboutthebolts 25 sufficiently to take them out of register with said head,the holes 26 inthe right-hand ends of the bars being considerably largerthan the bolts 25v to permit the necessary freedom of angularmovement'of the bars.

The slots'24 in the head 12 are considerably wider than the thicknessofthe bars and the latter are therefore capable of swinging in anydirection. When the shaft 14 is re tracted as far as it will go, theleft-hand edge of the cloth-board is removed from the clamping member 38and the cloth-board with the bolt of cloth thereon may therefore pewithdrawn from the left-hand ends of'the ars 15.

After the cloth and cloth-board have been removed, the lett headeasle atteeters may be placed back in the head 11 as shown, this operationinvolving the return of the lever to the position shown. An emptycloth-board may be put in the holding means by placing the left-handedge in the groove of clamping member 38, moving the board to the leftbeyond the members 35, and placing the right-hand edge of the boardbetween the lips 36 and bars 15 as shown by Figs. 2 and 6. When theseoperations have been performed the board and the winding machine areready to wind another bolt of cloth.
